Abstract:AIM:To explore the difference and correlation between different axial length and Anterior Chamber Depth(ACD) by means of IOLMaster and A ultrasound in the clinical cataract patients.METHODS:Cataract patients were collected for 8 months and examined respectively preoperatively by IOLMaster and A ultrasound.The results of both examinations were checked.Every patients were examined by the same skilled doctor.The axial length and ACD were examined by IOLMaster in first step,and then by A ultrasound in second step.RESULTS:There was some significant difference in the axial length <22mm,and no difference in the axial length >26mm and between 22mm and 26mm.A ultrasound and IOLMaster axial length relationship were 0.998,0.991 and 0.783.The correlationship about their ACD were 0.851,0.628,0.673.CONCLUSION:It was found that the IOLMaster’s axial length was longer than A ultrasound.There have good relationship among three groups about their axial length and A ultrasound,though there are some difference.
